PEN ATTACHMENT.

Application filed October 12, 1922, Serial No. 594,123. Renewed October20, 1926.

My invention relates to improvements in pen attachments, and hasparticular reference to an attaclnnent carried in the cap of theordinary fountain pen.

An object of my invention is to provide an eraser that is adapted to becarried by the cap of the ordinary fountain pen and which, when not inuse, may be swung out of an operative position.

A further object of my invention is to provide a pen attachment thatwill not 1nterfere with the ordinary uses of the pen and which may beswung into and out of an operative position at case when so desired.

A still further object of my invention is to provide a pen eraserattachment that is strong, durable, simple and inexpensive inconstruction, and that is well adapted to the use for which it isdesigned.

Other objects and advantages of the invention will become apparentduring the course of the following description:

In the drawings, wherein like numerals are employed to designate likeparts throughout the same,

Figure 1 is a perspective view of a fountain pen, showing the eraser inan operative position,

Figure 2 is a top plan view of the same, showing the eraser in aninoperative position,

Figure 3 is a section taken on line 3-3 of Figure 2, and

Figure 4 is a bottom plan of the eraser removed.

In the drawings, wherein for the purpo::e of illustration is shown apreferred embodiment of my invention, the numeral 5 designates anordinary form of fountain pen, which is provided with the usual cap 6.The cap 6 may be, if it is so desired, a little longer than the usualcap, so that my attachment will not interfere in any way with the penpoint when same is inserted Within the cap.

The cap 6 is provided with a longitudinally extending slot 7 and atransverse slot 8 extending substantially one-half the diameter of theend of the cap. A metallic strip 9 is adapted to be received within theslots 7 and 8, said slots 7 and 8 being wide enough to allow themetallic strip 9 to be bent back upon itself as clearly shown in thedrawings, and the sides thereof being in spaced relation. The ends ofthe strips 9 are bent angularly and small screws or the like 10 arepassed through the angular extensions 11 into the cap 6 to hold thestrip firmly in place. An angular lip 12 is also provided, and a screw13 is passed therethrough into the cap 6 to more firmly hold the strip 9in place.

An eraser member 14 which is carried on a shank 15 is adapted to bereciprocated' between the sides of the strips 9. As is clearly shown inFigure 4 of the drawings, the end of the shank 15 is provided withintegral diametrically opposed lugs 16 and 17 which are adapted to ridealong the lower edge of the strip 9, said strip 9 being provided withthe ofl-set notches 18 and 19, respectively, to receive thediametrically opposed lugs 16 and 17 whenever the eraser element 14 isin an operative position. At the juncture of the erasing element 14 andthe shank 15, similar lugs 20 and 21 are provided to more rigidly holdthe erasing element when the same is in an operative position. Anupstanding pin 22 is mounted near one end of the shank 15, and a knob 23is mounted thereon. A coiled spring 24 is adapted to be mounted on theupstanding pin 22 and a washer 25 is adapted to overlie the slot and toride along the upper edge of the strip 9 as will be readily understood.

It will thus be seen that normally the erasing element 14 will be in aretroactive position as is clearly illustrated in Figure 3 of thedrawings. When it is desired to use the erasing element 14 the knob 23is pulled to retract the s ring 24 thereby disengaging the diametricallyopposed lugs 16 and 17, and the knob 23 is moved outwardly until thediametrically opposed lugs 16 and 17 are adapted to be seated within thenotches 18 and 19. When the erasing operation is over, the knob 23 isagain detached and the erasing element 14 may be swung out of anoperative position. It will also be seen that I have devised a veryefiicient erasing attachment for fountain pens which may easily be swunginto and out of an operative position and which will not in any Wayinterfere with the'usual operation of a pen.

It is to be understood that the form of my invention herein shown anddescribed is to be taken as the preferred embodiment of the same andthat various changes in the shape, size and arrangement of parts may beresorted to without departing from the spirit of m invention or thescope of the subjoine claims.

Having thus fully described my invention what I claim is:

1. A device of the class described including a hollow handle having alongitudinally extending slot and a transverse extendin slotcommunicating with the other slot an positioned in its end, a U-shapedmember positioned inthe hollow handle having its ends projected throughthe second mentioned slot and bent to provide angular extensions fixedto the end of the handle, said member provided with notches, an eraserhaving projections for enga ing the slot and means on the eraserprojecting from the first mentioned slot whereby the eraser may bemovedto dis-V engage its projection from the notches and movelongitudinally of the handle either in a projected position or awithdrawn position.

2. A device of the class described includ ing a hollow cap member havinga slot' formed therein, a U-shaped guide member positioned in the saids'lot having angular projections at the extremities for securing same tothe said hollow cap, means formed on the U-shaped member for limitingthe movement of a movable member, an eraser having pro'ections for engaing the limiting means orined on the U- aped member and means forslidably actuating the said eraser in a .pro'ected or enclosed position.

3. A device 0 the class described including a hollow cap member having aslot formed therein, a U-sha ed guide member positioned in the cap adacent the said slot, projections formed on the extremities of the guidemember for securing same to the cap, means formed on the said U-shapedmember for limiting the movement of a member slidable therebetween, aneraser member slidably mounted in the U-shaped guide,pro-

jections formed on the eraser adapted to engage limiting means formed onthe U- shaped guide member, and aprojection adapted to slidably actuatethe eraser.

. In testimony whereof I aflix my signature. v
